Same songs re-synced to iphone every time

Next sync, the number dropped to 812.

I have worked around the problem. I noticed that many of the song names flashing by were spoken word audio instead of music, so I decided to stop syncing them.

I went into the finder and changed the Music settings for the phone. I changed it from "Entire music library" to "Selected artists, albums, genres, and playlists." Then I included all genres EXCEPT those that contained spoken word instead of music.

Next sync, voila! No unnecessary syncing!

Still curious why!

Thanks once more!

Thanks for the idea, it is intriguing. I created a smart playlist for all songs with data in the Work field. There are 382 of them. The songs being re-synced every time is 823. So that may be part of the problem. I tried to clear the Work field, but I don't know how. And I suspect it won't solve the problem, but it might give me another clue.

Since I last posted, I was able to turn on Use Work & Movement for all the songs, then clear the Work field, then selecting all songs modified today, turn off the Use Work & Movement. Then I did a sync. This time, it only re-synched 822 songs. I'm not sure if I learned anything at all.

Does anyone know a way to troubleshoot this?

Thanks

Thank you SO much for helping me with this!

I set permissions as described in your article. This did not have an effect. Still re-synching the same songs.

I read about Multiple Tags, and would like to try that. Is there a way to select (by smart playlist or otherwise) the files that might need tags removed?

Thanks again. I really enjoyed your article.

Thanks for the idea. I tried it on 128 songs. Question: When you said convert ID3 Tags to None, you said "a few times." How many times is necessary? I only did it two times on the 128 files before rebuilding the tags as you instructed.

I have proof that some of those 128 were (are) re-synching over and over. But still no change. Still re-synching 822 songs every time. Any other ideas? (I waited several days and several syncs to make sure it wasn't helping.)

I have been trying to note the names of the songs as they flash by. Everyone I have checked is .MP3 with a sample rate of 44.1 kHz.

Thanks again. I took a subset of the files and checked to make sure that the "more info" section of "get info" was empty before putting back the V2.3 tag.

I will report back after a day or so. Need to sync twice to see if it helps.

I appreciate your help. I wish I knew the algorithm that decides which songs to sync and which not, as that might help me narrow it down. I know SSDs have limited life, shortened by writing, and I would rather my phone SSD not be compromised by all this writing of songs unnecessarily.

Anyway, I truly appreciate your time.

I can't say exhaustively because I don't know how to identify all 822 songs. However, the ones I have been able to check (by watching the names fly by during sync) are NOT duplicated. By that, I mean they are not repeated in the iTunes (Music) data, AND are not duplicated files on disk.

Once again, thanks for your help!
